The "Bims," as their fans and friends affectionately call them, have been accompanied for 15 years by Brad Franck on drums. The show is an ever-changing rock 'n' roll comedy act, with pianist Middleton and guitarist Lewis playing timeless songs (originals and covers), drinking beer (from orange construction cones), a lot of self-deprecating humor and lots of antics.

The show is unscripted, and the duo bounce off each other and the audience.

"You don't watch the Bims, you experience the show," said Dave Deaver, former owner of The Intersection when it was in Eastown. "They are rare local treasures, and their humor is timeless."

How has the act changed?

"Gravity has changed over the last 25 years," Middleton said, "We are growing older -- but not 'up.'"

The funny, rockin' Bimini Brothers was officially brought to life in 1983, although the guys already had played together for a decade by then.

Deaver described Middleton as an "unbelievably talented songwriter and musician" and Lewis as "the typical Hemingway stoic bass player -- and a hand grenade of humor, with (Middleton) as the catalyst."

"When I'm playing, and I look out at the crowd and people are laughing and enjoying themselves, I'm still amazed," Lewis said. "The crowd takes us on our journey."

For Middleton and Lewis' 25th anniversary celebration, the Bims will entertain as only they can.

"It's all about making people laugh and have a good time," Franck said.
